Defining Response Criteria for PET Scans for People With Neuroendocrine Tumors

July 22, 2026 updated by: Memorial Sloan Kettering Cancer Center

Definition of PET REsponSe CrItEria for Neuroendocrine Tumors (PRESCIENT)

People with neuroendocrine cancer typically have imaging scans before and after treatment, including positron emission tomography (PET) scans. The scans are analyzed using a set of criteria that describes how the disease has responded to treatment. The purpose of this study is to establish new criteria for doctors to use when evaluating these PET scans. Researchers are testing whether these new criteria are useful for predicting whether a person's cancer gets better, gets worse, or stays the same. Researchers will also compare these new criteria to the current standard criteria for evaluating imaging scans.

Study Population

Potential research subjects will be identified by a member of the patient's treatment team, the protocol investigator, or research team at Memorial Sloan Kettering (MSK).

Description

Subjects affected by histologically proven, somatostatin-receptor positive, metastatic or inoperable well-differentiated G1, G2 or G3 neuroendocrine tumors (NETs) candidate to receive PRRT with 177Lu-DOTATATE per standard of care.

Inclusion Criteria:

  1. Histologically proven or cytologically confirmed, metastatic or inoperable NETs
  2. Measurable disease as defined by RECIST 1.1.
  3. Overexpression of somatostatin receptors of the target lesions at somatostatin receptor imaging (68Ga-DOTATATE or 64Cu-DOTATATE PET/CT) with SUV of lesions greater than normal liver at least in 1 metastasis.

Exclusion Criteria:

  1. Neuroendocrine Carcinoma), small and large cell type; MIxed Neuroendocrine-Nonneuroendocrine Neoplasm (MiNEN).
  2. Presence of somatostatin receptor negative lesions.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
validate the PRESCIENT criteria
Time Frame: 1 year
On this prospective validation cohort, the prognostic value of each criteria for the 1-year PFS will be assessed, using a Cox regression model (stratified on the site) and the area under the receiver operating curve (AUC) for time-dependent outcome using inverse probability of censoring weighting.
